Half the distance from the wall to the centre of the luminaire, as the distance there is between luminaires. e.g if the distance between luminaires horizontally is 3m then the distance to the centre of the luminaire from the wall is 1.5m. If the distance between the luminaires vertically is 5m then the distance to the centre of the luminaire from the wall is 2.5m

Hiow to find space to height ratio?
Spacing Height Ratio is defined as the ratio of the distance between adjacent luminaires (centre to centre), to their height above the working plane. If you know SHR and the height, the distance apart D is pretty straight forward. You then need to check absolute limits such as SHR (Transverse), SHR (axial) and SHR Max. You can also use the following as a quick means check: SHR(Nominal) = (1/Hm) x (Square root(Area/N)) Where Hm is mounting height, N is number of luminaires. Regards
How is a glide ratio calculated?
To calculate the glide ratio, you divide the length it was thrown, e.g. 150cm, by the height it was thrown, e.g. 50cm. So 150/50=30cm so, it would be 30:1.
Is it true that a ratio is a rate?
No. It can be but need not be. For example, you might calculate the ratio of today's temperature in Celsius and in Fahrenheit and calculate the ratio. That is not a rate.

How do I calculate the distance between current location and a distant visible object if the only information available is the height of the object and the distance between 2 fingers at your eye?
The ratio of the spacing of the fingers and the distance from your eye will be the same as the ratio of the height of the object to its distance from you, so Hf/Df = Ho/Do and Do = HoDf/Hf
What mathematical equation can be used to calculate the ratio between the drop height and the first bounce height?

How do you calculate the aspect ratio of a duct?
The aspect ratio of a duct can be evaluated as the ratio of width to height. As the aspect ratio increases, vibration noise, friction and cost also increases.

How you calculate lighting efficiency?
To calculate lighting efficiency, you can use the formula: Efficiency = Lumens / Watt. Lumens represent the amount of light emitted, and watts measure power consumption. By dividing the lumens by the watts used, you can determine how efficiently a light source converts electricity into visible light. The higher the lumens per watt ratio, the more efficient the lighting.
How many kilogram do you have to be to be an anorexic?
It's not that simple ! It's the ratio of your weight to your height that's used to calculate whether you're anorexic or not.
What does the height base ratio mean?
The ratio of the height of an object to the length of its base.

The radii of two circular cylinders are in the ratio 2 3 and their height are in ratio 5 4 calculate the ratio of their volumes?
Let the radius of the first be 2r; then the radius of the second is 3r Let the height of the first be 5h; then the height of the second is 4h volume cylinder = π × radius² × height → volume first = π × (2r)² × 5h = 20πr²h → volume second = π × (3r)² × 4h = 36πr²h → ratio of their volumes is: 20πr²h : 36πr²h = 20 : 36 (divide by πr²h) = 5 : 9 (divide by 4)
